Majorana correlations in quantum impurities coupled to a topological wire
G. S. Diniz, E. Vernek
In this work we investigate Majorana correlations in quantum impurities coupled to a topological superconducting wire. By employing a density matrix renormalization group approach,…
Topological nature of in-gap bound states in disordered large-gap monolayer transition metal dichalcogenides
Fanyao Qu, L. Villegas-Lelovsky, G. S. Diniz
We propose a physical model based on disordered (a hole punched inside a material) monolayer transition metal dichalcogenides (TMDs) to demonstrate a large-gap quantum valley Hall…
Graphene-based spin switch device via modulated Rashba field and strain
G. S. Diniz, E. Vernek, F. M. Souza
We investigate the spin-resolved transport in a two-terminal zigzag graphene nanoribbon device with two independent gate induced Rashba spin-orbit coupling regions and in the prese…
Zero-field and time-reserval-symmetry-broken topological phase transitions in graphene
Marcos Rafael Guassi, Ginetom Souza Diniz, Nancy Sandler +1
We propose a quantum electronic device based on strained graphene nanoribbon. Mechanical strain, internal exchange field and spin-orbit couplings (SOCs) have been exploited as prin…
Controllable Spin-Charge Transport in Strained Graphene Nanoribbon Devices
Ginetom S. Diniz, Marcos R. Guassi, Fanyao Qu
We theoretically investigate the spin-charge transport in two-terminal device of graphene nanoribbons in the presence of an uniform uniaxial strain, spin-orbit coupling, exchange f…
Spin-orbit coupling and the static polarizability of single-wall carbon nanotubes
Ginetom S. Diniz, Sergio E. Ulloa
We calculate the static longitudinal polarizability of single-wall carbon nanotubes in the long wavelength limit taking into account spin-orbit effects. We use a four-orbital ortho…
Engineering the Quantum Anomalous Hall Effect in Graphene with Uniaxial Strains
G. S. Diniz, M. R. Guassi, F. Qu
We theoretically investigate the manipulation of the quantum anomalous Hall effect (QAHE) in graphene by means of the uniaxial strain. The values of Chern number and Hall conductan…
